New Microchips Shun Transistors
`For the first time, researchers have created a working prototype of a radical new chip design based on magnetism instead of electrical transistors.
As transistor-based microchips hit the limits of Moore’s Law, a group of electrical engineers at the University of Notre Dame has fabricated a chip that uses nanoscale magnetic “islands” to juggle the ones and zeroes of binary code. [..]
Because the chip has no wires, its device density and processing power may eventually be much higher than transistor-based devices. And it won’t be nearly as power-hungry, which will translate to less heat emission and a cooler future for portable hardware like laptops.’
